I read with great interest the article entitled: A Global call to Action on Chronic Diseases by Christine Gorman. Ms. Gorman cites possible causes as to why cancer rates have increased in developing countries. She included adoption of Western society type diets. If you look at the specific cancers that have increased in almost every country, breast and prostate cancers lead the pack. Western diets have consistently been to blame for increased cancer incidence in developing countries. What could be the specific components of a Western diet that cause an increase in hormonally sensitive cancers? It seems obvious that we should look at hormones. What foods contain large amounts of the hormones associated with development of these cancers? Of course, it is dairy and its' increased consumption parallels the increase in these hormonally sensitive tumors. Dairy is loaded with the essential components necessary to cause these cancers: estrogens and insulin-like growth factor one.- Robert D. Bibb, M.D., Myrtle Beach,S.C.
